Cascade Stainless Solutions were recommended to me by G4 Kegs, and I am so happy we decided to purchase our keg washer from them.
Our brewery, Great Falls Brewing Co., is a small brewery in Connecticut with a 10 BBL brewhouse and one brewer doing everything from compliance and reporting to washing kegs and making beer. The semi-automatic 2 head keg washer we bought in Summer 2018 was a good deal compared to the rest of the marketplace, and even better when you factor in all the saved labor hours. When calculating my own labor, I don't even include keg washing because I always do it concurrently with other tasks- just set it up, get some kegs on and walk away to do something else.
Another pro for their system are the recipe design features that let you determine how many caustic rinse repeats, purges, sanitizer rinses, how long you want your CO2 purge, and more. It means you can have repeatable, tailored keg washing results.
I trained a local 'will-work-for-beer' volunteer on the keg washer in about 10 minutes and they had 30 kegs washed in no time. Try training someone with no brewing experience on a manual keg washer in that amount of time and actually feeling good about the results. The CSS machine has an intuitive touch screen interface that, once you set it up, can be run by pressing one button(!).
On top of machine quality, the customer service has been on point. Kyle was with me every step of the way from my first inquiry, through manufacturing, shipping and start-up. Great machines, great company. I recommend them.
